You’re right. The source video is also h.264. There are also those black artifacts in the original video, bet they aren’t so slightly visible. I’ve made this project of various clips with different quality and those black artifacts after rendering are visible across all the video, now even in scenes where black color quality in source material was top-notch.
Usually I rendered in h.264 using these settings:

1920×1080
Frame rate: 23,976
Field order: Progressive
Aspect ratio: Square pixels(1.0)
NTSC
Main profile
Level 4.1
VB2, 2 Pass
Target bitrate: 6 Max bitrate: 8

Keeping everything as close to source material as possible. But now when I render in these settings, video seems to render as casual, but in the destination folder there’s just .mp4 file in size 24 bytes, consisting of error smt like this “Format file can’t be described”

So I decided to choose “Match Sequence Settings” and Premiere Pro renders it in .AVI format, but with those black artifacts. And, of course, massive in size.

.AVI settings:
IYUV codec
1920×1080
Frame rate: 23,976
Field order: Progressive
Aspect ratio: Square pixels(1.0)
Depth 24 bit

These are standard settings Premiere Pro gives me when I choose to have “Match Sequence Settings”

Most likely, I could resolve this problem if someone could answer, why Premiere Pro renders h.264 file in size 24 bytes with error? I’ve looked upon net, there are people complaining about this also, but no answer how to fix or why does it occurs.

I am using Adobe Premiere Pro CC.

I know this may sound a foolish question, but it comes from somenone who’s not working with AE on daiy basis.

Where can I find Quick Mask tool?

I’m used to regular way: Layer/Mask.
